Explosion proof lamps cannot use ordinary light bulbs. The design purpose of explosion-proof lamps is to provide safe and reliable lighting in hazardous and flammable environments, and ordinary light bulbs cannot meet these strict safety requirements.

Ordinary light bulbs may generate high temperatures, sparks, or arcs during normal operation. In explosion-proof environments, these phenomena may ignite surrounding combustible gases, vapors, or dust, leading to explosions or fires and causing serious casualties and property damage.

Explosion proof lamps are usually equipped with specially designed explosion-proof bulbs or light sources. These light bulbs are specially processed and manufactured to ensure that no dangerous heat sources, sparks, or arcs are generated during operation. Their structure and materials can limit the release of energy and reduce the risk of explosion.

In addition, the overall structure of the explosion-proof lamp, including the housing, sealing components, circuit, etc., is designed to complement the dedicated light bulb and form a complete explosion-proof system. If ordinary light bulbs are installed in explosion-proof lamps, their explosion-proof performance may be compromised, leading to protection failure.

For example, in a coal mine, if ordinary light bulbs are used instead of explosion-proof bulbs, even a small bulb malfunction can cause a gas explosion, endangering the lives of miners.

Moreover, using ordinary light bulbs may also result in explosion-proof lamps being unable to pass relevant safety certifications and inspections. This not only violates safety regulations, but also poses significant potential hazards to the workplace.

In summary, in order to ensure the safety of personnel and equipment, specially designed explosion-proof bulbs must be used in explosion-proof lamps, and ordinary bulbs cannot be used arbitrarily.
